There's a comment header for dm_send_unmount_event() that talks about some
issues with this being a synchronous event.  The spec still says it
is synchronous:

http://www.opengroup.org/onlinepubs/9657099/toc.htm

This looks like another case where the spec can cause a headache.

Maybe if the event is raised sooner, before the dmapi handle is disabled, this could solved the issue. (dm_path_to_fshandle() should still be runnable as long as the unmount event was not replied, or, at least, delivered but in outstanding state).

I have't look at the code, i don't know whether it is possible or not.
